The biggest problem is the rich have created a system in which people's future (retirement) is basically linked to "the market" growing over their lifetime. And the hopes that if they get lucky enough with the market they can retire early (or at all). This system of course is built 100% on governments/employers not wanting to guarantee financial security of elders and offload the risk to the individual. Also the rich have a massive incentive for everyone to "invest" (cough) and drive prices up, because the rich benefit insanely more by market movements than a standard person does.
Maybe the system will explode in our lifetime, maybe not. But all this insanity focus of growth, profits, etc with no genuine regard to real social issues (providing basic stability to people whether it be healthcare, housing, food, childcare) is so sick I can barely even think about it. And there's almost nothing to do about it- that's the way things currently "work" and it seems insurmountable to do anything about it.
